What are the incompatibility issues of blood group type o positive: girl & b negative: boy in marriage?

Will there be any complications in pregnancy & while giving birth?

No. There would have been had the blood types been reversed. Even then they have shots for it.  (+ info)

surrogacy mother and ABO blood group incompatibility?

I am a male , my blood type is AB+ , my wife is B+, the surrogacy mother is O+.
The fertilized egg cell will be placed into the surrogacy mother 's body.

The surrogacy mother is 21 yrs old, have no history of pregnancy.
I want to know if the ABO blood group incompatibility will happen and the rate of ABO incompatibility? If it really happens, is there any treatment method to prevent it become more serious?


There should not be any problem. Typically, the only problem stems from a "mother" who has a negative blood type and the fetus has positive. Then she receives shots of Rhogam to counteract the problem. As for her being O, there shouldn't be a problem there either. I understand your concern, but you should speak to the doctor about this and find out what s/he says. I don't think it would be any difference blood-wise than a woman who is O mating with a man who is AB. Most likely, the child will turn out B+, but you never know! Good luck!  (+ info)

blood group !?

my blood group is AB negative...and i have noticed when i tell anybody about my blood group, they be a bit surprised and say 'oh god u r AB negative' ! and ppl even say tht dis blood group is not safe for a pregnant women. is it true?

AB is a rare blood type but that has nothing to do with pregnancy. Being Rhesus negative can be a problem if your baby is Rhesus positive, which is may be if your husband is positive. The first pregnancy is usually not effected but in subsequent pregnancies the mother may develop antibodies to the positive blood causing her body to try to kill the baby like an infection. These days they give Rhesus negative women who are pregnant an injection to stop this problem. Don't worry, modern medicine can deal with many issues which years ago would have been a real problem. Talk to your doctor about this.  (+ info)

I need your help on Blood Group factor incompatibility. Please, it's about our lives !?

I m 23 yrs and AB positive and my wife is 25 yrs and B Negative. One year ago, when she got pregnent first time, it was about 10 weeks and she miscarried it. By that time, we knew nothing about Rhogam or anything like that, so we din't take any shot. But now, when we came to know about it, we are worried. will she ever be able to be a mother ? is there something which can help us ? is there any ray of hope ? God bless all of you.

Yes there are lots of mothers out there who gone on to have many healthy pregnancies.  (+ info)

Blood group ????

I am pregnant and have AB negitive blood and have been told i will have injections for this.... I really dont understand why..... can any one shed any light on this situation?

If the father has rh positive blood, or if you don't know the father's blood type, then you will need injections of rhogam to make sure your body does not make antibodies that could attack the baby. If this is your first pregnancy, then it's generally not a concern for this baby, but more for any future babies you may have. It's very routine. I'm also rh negative, but so is my husband, thus no need for the shots.  (+ info)

what is the different between AB negative and AB positive blood group?

Is AB negative is good blood? Those with AB negative can donate blood or are they in there sickness or normal life? What blood group are there in human blood? What blood group are there in animals blood? What blood group are there in dinosaur blood? Is there anyone with all the blood group type? Why is it that someone with different blood group type can't give to that person with different blood group type? Same blood right!!

My dear John...

NO !!! It's not the way you've mentioned in your last sentence...Blood is NOT..."blood"...There are (slight) differentiations in the various blood types...and quite complicated to explain with the allergens, etc. However here is some basic information on the subject:

Normal red blood cells are recognized as “self” so we don’t have antibodies against our own cells. However, we will have antibodies against the red blood cells of other people’s blood if their cell surface carbohydrates are different from ours. This is the basis of ABO blood group and it’s why we have to match blood types in a blood transfusion.

The ABO blood group was discovered over one hundred years ago by Karl Landsteiner (Nobel Laureate: Karl Landsteiner). The biochemical basis was only elucidated in the 1970’s when the technology for examining the carbohydrate structure of glycoproteins was worked out.

There’s an allele of the A enzyme gene that involves only a very small number of mutations but the result is to switch the enzyme from one that transfers GalNAc to one that transfers galactose (Gal). The variant enzyme is called B enzyme (galactosyltransferase) and the B antigen structure has a terminal galactose (Gal) instead of a terminal GalNAc.

If you are homozygous for the B allele on chromosome 9 then all of your red blood cells will have the B antigen oligosaccharide on their surface. You will not make antibodies against this structure because it’s “self.” You also won’t have antibodies against H-antigen for the reasons explained earlier. But you won’t recognize A antigen as self so your antibodies will attack any foreign cells that come from people with the normal wild-type allele (A).

People with blood type A will have antibodies against B antigen. They can receive blood from people with O blood type but they will reject blood from people with B blood type. You now have all the information you need to figure out who can give and receive blood from every possible combination of alleles: AA, AO, AB, BO, and OO.

There are no known natural effects of these differing blood types. People with A, B, AB and O phenotypes do not differ in fitness in any major way that we have been able to detect. This suggests that the complete absence of the enzyme (null mutation) is neutral in the current human population and so is the switch from one form of the enzyme to another. (Suggestions that blood type determines susceptibility to some infections are common in the scientific literature. Most of them have not held up. The best correlation is a possible association between blood type O and susceptibility to cholera. This looks pretty good but the cause-and-effect relationship is still up in the air.)

The ABO alleles seem to be segregating in the human population by random genetic drift. The O allele (non-functional enzyme) is the most common allele. The B allele is the least common—probably because it arose more recently. Some Native American populations are homogeneous for the O allele; in those populations everyone has blood type O. (For maps of the frequencies A and B alleles see Distribution of Blood Types.)

There are a total of 4 blood types, which are : O, A, B, and AB
The : o-type is the most common of the 4 and is able to donate to all 4 types ! BUT: type A and type B can only donate to the AB-type !

Your Q. about the "pos./neg." part pertains to the "Rhesus factor" and some rare people have "rhesus factor negative", but most have "rhesus positive" ! All these factors are important for a blood transfusion because you can NOT give a "rhesus positive" person the blood from a "rhesus negative" person....and there's many more on the subject to be found in the internet under :

Hope this was giving you some answers to your Q. - and- what the hell do you care about and "animal"(dinosaur's, etc.) anyway...??? That's a total different subject and has NOTHING to do with our "human blood" baby ! Send you all my love & care....Annette***  (+ info)

Which blood group of a female is compatible for a man with AB -ve blood group for marriage & conceiving child?

My blood group is AB -ve. Many of my friends, relatives & some of the doctors have told me that since I have negative blood group, I have to cautious at the time of marriage, so that there would be no problems at the time of conception & delivery by my probable wife. Nobody has yet told me exactly which blood groups are acceptable for me as my wife's blood group.
Please, can anybody tell me, which blood groups are acceptable to me? Also, suggest me some web sites or web pages to look into.

marry a chick with like o - , a - , b - , ab - you know? marry a chick with negative blood lines like you so you can have negative children together so she wont have to get rh shots during her pregnancy  (+ info)

What is the different between blood type and blood group?

Is there any different between blood type and blood group? if yes what is it? My blood type is O+, so how do I know my blood group?

There is no difference. 'Blood group' is the older phrase, but 'blood type' is used more often now, perhaps because of the discovery of rare types (if there are only two people in the world known to have a type, that's not much of a group).

Your blood type: O and Rhesus D positive means that you have neither the A nor the B antigen on your red blood cells, but you do have the Rhesus D antigen (you're 'positive' for it). Therefore you almost certainly have anti-A and anti-B antibodies, but won't have anti-Rh antibodies.

You could receive a transfusion of red blood cells from O+ or O- types, and blood plasma (especially used for burns victims) from any positive type (AB+, A+, B+ or O+).

It's unlikely either of your parents is an AB type, or that they are both negative (though to be honest, neither was that likely anyway).  (+ info)

What is the biggest blood group in the world?

I just want to know what is the biggest blood group, in term of number, of the human population in the world? I heard it was B 1st, then followed by A, O and the last is AB. Or does it depend on certain races?



Least is AB-  (+ info)

What year did it become routine to record newborns blood group in the UK?

I want to know my blood group, and I seem to recall my GP not knowing. I don't want to have to pay £15 for a test to find out if i can request my hospital records to find out. I have a daughter and I know they routinely check blood groups of newborns now. WHat year did they start doing this?

If you donate blood, they will send you a notice telling you your blood group for FREE. I know that they do this in the UK as well as the US.  (+ info)
